Eine ökologische Hühnermast mit "100-%-Bio-Futter" ist möglich

The purpose of the present study was to test an organic feed for chicken production. Different feed mixtures with reduced dietary energy level (< 12 MJ AME/kg) and reduced content of essential amino acids were investigated. In case of reduction a constant ratio of amino acids to energy was considered. Under the future European law for organic products all raw materials used for the feed were of organic origin. The feed consumption of the different feeding groups ran conversely proportional to the diets energy level. The obtained fattening performance and carcass yield reached a high level under the circumstances of organic production

Einsatz von unterschiedlich wärmebehandelten Sojakuchen in der ökologischen Hähnchenmast

In an interdisciplinary research project the following questions are to be examined: 1. How are the treatments common in practice (thermal, hydro-thermal and pressurethermal treatment) to be rated in terms of the removal of anti-nutritive active factors (ANF) in soy bean cake? 2. Which input of soy bean cake (treated) can be recommended for practical feeding in organic broiler production? Results and conclusion: 1. All treatments are sufficient for removal of ANF in soy bean cake. 2. For feeding mixtures in organic broiler production a content of 20 % (starter) or 15 % (finisher) soy bean cake can be recommended
